pF 1000 pF 1000 pF C2 C3 Ringing Excessive ringing (long acquisition time) may occur with large capacitive loads This may be reduced by isolating the capacitive load with a resistance of 100X Large source resistances may also give rise to the same problem and this may be decreased by the addition of a capacitance across the feedback resistance A value of around 50 pF for unity gain configuration and around 3 0 pF for gain 10 should be adequate Latch Up This may occur when the amplifier is used as a voltage follower The inclusion of a diode between leads 6 and 2 with the cathode toward lead 2 is the recommended preventive measure Note For gain 10 compensation may be simplified by removing C2 C3 and adding a 200 pF capacitor (C4) between Lead 7 and 10 Typical Applications Frequency
